悬架系统是汽车中十分重要的系统之一，尤其在轿车这一类注重舒适性的汽车，驾驶感与乘坐舒适感，直接影响了客户对于汽车整体的满意度，在汽车的设计研发的过程中也越来越重视悬架系统的调教，可见轿车悬架系统的设计就尤为重要了。
本文介绍了悬架系统的设计要求，针对小型轿车进行悬架系统的设计及仿真分析，包括通过对比各类悬架的特性以及轿车自身性能和成本要求对前、后悬架类型的选取；为满足设计要求对悬架静挠度等参数进行计算优化，弹性元件的几何参数设计以及受力分析的校核，减震器类型的选择和相关参数的设计，并利用计算机软件对悬架机构进行了三维建模，通过悬架的运动方式进行了运动仿真以及主要零件的有限元分析。

Abstract
 
Suspension system is one of the most important systems in automobiles, especially in the car this kind of attention to comfort of the car, driving sense and ride comfort, directly affect the customer satisfaction of the overall car, in the design and development of the car also more and more attention to the suspension system, visible car suspension system design is particularly important.
This paper introduced the design requirements of suspension system,  the design and simulation of suspension system for small car are carried out in this paper, including the selection of the pre and rear suspension types by comparing the characteristics of various types of suspension and the requirements of the car's own performance and cost, in order to meet the design requirements, the static deflection parameters of the suspension are optimized, The geometrical parameter design of elastic element, the checking of force analysis, the selection of shock absorber type and the design of correlative parameters, and the three-dimensional modeling of suspension mechanism by using computer software, the motion simulation and the finite element analysis of main parts are carried out through the motion mode of suspension.
Keywords: suspension; spring; shock absorber; modeling; finite element analysis
